• Fixed save game functionality. Experimental, please report any issues.
  
• AI fog of war vision adjustments:
  
  • Implemented unit 'last spotted time' functionality.
    
  • Reworked all indirect fire position filters to utilize 'last spotted time' information. AI will now be able to temporarily 'see' units which have disappeared into fog of war.
    
  • Reduced vision of units in fog of war which haven't been seen recently.
• Fixed an issue where all randomness was not working in the mod (this issue is present for all game mode scripts). Randomness in the mod would always chose the threshold lower bound outcome. The fix should result in more varied AI behavior, particularly relating to unit choices, but almost every aspect of the mod will be affected to a degree.
  
• Reduced AI propencity to barrage low HP vehicles. This also affects how often it bombards low hitpoint vehicles in fog of war. Hopefully the change will rede the feeling that AI knows perfectly when to barrage under-repair vehicles.

- Reworked many aspects of cover search algorithm:
* Improved precision.
* Properly handling yellow-cover-providing objects by scanning for these objects manually instead of utilizing engine's cover value functionality which was not working for many cases.
* Properly handling terrain cover - terrain cover is no longer affected by direction modifiers.
* Reworked many parameters for searching for cover from scratch, utilizing multiplicative modifiers instead of relying on additive scoring.
* Added exponential scaling of many of the scoring levers.
* Introduced the concept of cover direction similarity, in effect making AI choose areas in the middle of cover more effectively, as well as properly utilizing sandbag cover, which previously wasn't handled correctly.
* Fixed issues where areas where there were many cover-providing objects were considered much better cover than they were in reality.
* Introduced the concept of impass-searching the final command position, making AI hug cover much more precisely.
* Introduced the concept of max cover value, allowing to better differentiate between different levels of cover overall.
* The algorithm is now flexible enough to be used for functionality such as finding good sandbag and barbed wire locations.
* Adjusted search radii which should hopefully result in AI taking cover more quickly overall instead of moving to a far away perfect cover location.

- Fixed pinning shot ability target search range.
- Fixed easy 8 having a canister shot ability and not utilizing its hvap rounds ability.
- Many internal systems have seen revamps and optimizations for futureproofing and overall code correctness.

- Vehicle behavior:
* Implemented most vehicle abilities into the mod (previously AI used only a few select ones and barrages).
* Implemented a safety modifier for vehicles during ability usage. This should let AI finish its barrages more often before retreating.
* Implemented US mechanized support center smoke barrages.
* Increased vehicle aggressiveness across the board.
* Implemented functionality to allow multiple vehicle prioritization abilities per unit, used the functionality for command tank AP rounds.
* Implemented Hellcat barrage.
* Fixed DAK Stug D getting forced facing commands.
- General safety assessment logic:
* Implemented functionality for AI to consider nearby vehicle top speed when considering their safety - AI should retreat from units like the 8rad much sooner.
* Implemented vision check - this should make it easier to ambush AI from fog of war, and it should especially make AI vehicles worse at avoiding AT guns it doesn't see, increase infantry aggressiveness slightly.
* Units which don't have any weapons that can range AI's unit will now be considered less dangerous.
* Adjusted various parameters in general.
- Avoidance functionality:
* Fixed AI completely ignoring player-used player abilities.

* Fixed a crash related to AI trying to avoid squad&entity-targeted player abilities.
- Special unit control:
* Fixed an issue where special units didn't calculate threat distance threat properly, resulting in them not pulling back from danger.
* Rebalanced many special unit safety parameters. Sniper in particular should now once again properly attack move forward and then pull back once pushed properly.
* Implemented functionality which now detects HMGs in progress of setting up properly despite engine limitations.
* HMG units are now allowed to attack move, making them much less likely to not react to meeting an enemy unit.

* AI will prefer barraging entities over squads.
* AI will no longer be able to see emplacements in fog of war for a certain duration of time.
* Adjusted AI fog of war data accruement parameters.
- Economy:
* Implemented multiple new settings for controlling how AI counters unit classes.
* Made many improvements to how AI counters armor early in the game, it should much more consistently be prepared for early vehicles.
* AI anti-tank class value no longer scales linearly, once AI saturates the field with AT, it should refocus on purchasing normal units even if the enemy keeps buying more armor.
* In cases where AI has less anti-tank than enemy has armor, AI will be forced to react much sooner.
* Implemented functionality which limits the AI from queuing too many units early in the game, the limits are based on total amount of resources AI has at the start of the game. This should improve AI unit composition in high resource start games drastically.
* Reduced the chance of picking currently worst possible but pickable choice.
* Slightly increased base count decay value - should result in AI spamming same units less often across the board.
* Emplacement and mine purchase priority now depends slightly on the total number of AI players in the game. This is needed because AI player count affects update frequency of engineer squads, so in lower player count games, AI would buy many more emplacements and mines compared to high player count games.
* Adjusted many class counter multipliers to generally improve AI unit compositions and countering.
* Adjusted priorities of many AT units to work properly with new multipliers and to achieve the desired effect of AI countering early armor better.
* Adjusted base emplacement purchase priority.
* Implemented an extra uniqueness radius check for some emplacement upgrades - emplacements like med bunkers should be much less likely to be placed near other med bunkers.
* Rebalanced emplacement class values, AI should counter emplacements better.
* Rebalanced ETA decay values.
* Reduced mine purchase frequency.
* Reduced US halftrack purchase priority.
* Reduced Wehr halftrack purchase priority.
